Very poor. Either Fire Fox or Amazon is using part of my email suryve........us@yahoo.cia...... and is exposing my password at Amazon. Remove Fiefox account and also the Amazon account immediately, or both Fiefox ans Amazon.comare history-no orders no $'s, period!

Does not improve search quality at all. I tested searching for "piracetam." Not one single item contained that word, or that ingredient. I know Amazon sells it, but you can't find it. It may be there, on page 25-50, but it's much easier to buy somewhere else.

It is a great add on but it would be better if I searched something and the results could be displayed in the assistant window itself rather than opening the Amazon site. And if one is interested in seeing on the site they can click on the icon 'open on the site'

It does help making purchase decision - when it works, sometimes this add would bring something totally irrelevant to what I'm viewing to compare with, other times the banner would popup and disappear in half second.
